I had booked flights for November 9 YYZ - JFK - LAX - PSP, including Delta One from JFK - LAX. Today, I was notified that my flights were changed due to a schedule change. I am now scheduled for YYZ - ATL - LAX - PSP but only in domestic first. The original flights are all available and all for sale, but when I search on delta.com for that routing it doesn't show as available, only domestic F is available for that routing.

Thoughts on what's going on and whether I can get the original flights reinstated? I have been waiting for 4.5 hours for the call back...
